Question 1.
What is a regime channel?
Show hintHide hint
Think about how it behaves over time with sediment.
Question 2.
Who developed the theory of critical velocity?
Show hintHide hint
Recall which theory originated from empirical studies.
3Question 3.

Show hintHide hint
Think about its limitations discussed earlier.
Question 5.
Assess the implications of using empirical equations for various sediment types beyond Lacey's original studies.
Show hintHide hint
Consider how sediment type affects flow and stability.
Question 6.
